An Android application called OpenCV_for_Tegra_Demo.apk demonstrates some examples of the optimization factors that can be achieved with OpenCV for Tegra versus OpenCV for Android on Tegra devices. This application is available in the <path to TADP directory>/OpenCV-2.4.8.2-Tegra-sdk/apk/ folder. The OpenCV_for_Tegra_Demo.apk application can also be freely downloaded from the Google Play store.
A sample screen shot of the OpenCV for Tegra Demo application is below.
Typical optimizations factors observed for the various modes of the demo application on the Tegra 4 device are listed below.
| Mode | Speedup (Tegra 4) |
|---|---|
| Median Blur | 23.7 |
| Gaussian Blur | 7.8 |
| Sketch | 6.9 |
| Morpho Gradient | 3.9 |
| Watermark | 3.1 |
| Sobel | 2.0 |
| Optical Flow | 1.5 |
